At least four civilians were killed and more than 15 others were wounded in a bomb blast during Eid al Fitr celebrations outside the Somali town of Baidoa, witnesses said.

The explosion occurred on Sunday afternoon as people performed traditional dances in a field near an internally displaced persons camp north of the town.

A security official who could not be named says celebrations were held in the field Saturday without incident.

He said he believes the bomb was planted before celebrations continued for a second day Sunday.

Earlier on Sunday, a police general survived a roadside explosion targeting his vehicle in Mogadishu.
